Question

Assume a parallel plate capacitor in which paper layer is kept with a goal of protecting conductors from one another. The insulator is impregnated with oil to give it a r. The oil used has a dielectric strength Vb = 20,000 V/mm. Assume the thickness of insulator in mm. For practical purposes of space, the insulator assembly is rolled as on a spool and placed in a protective shell. Assume E is uniform between the conductor. Find
(a) The capacitance of the device.
